Laser Extensometer EXT-66-LOE

Using a unique laser scanning approach developed by United Calibration Corporation, the United Laser Extensometer permits accurate non-contact extension measurement from the start of the test through sample failure without test interruption. Designed to provide accurate extension measurements from less than 1% to greater than 1000% strain, this versatile optical scanning device performs well for sample testing with an environmental chamber at elevated or even very low test temperatures, as well as at normal temperatures and environments.

The United Laser Extensometer is unique in its ability to measure a broad range of materials including ultra-high modulus carbon composites, ceramics, steel and non-ferrous metals, paper and wood products as well as most varieties of elastomers.

Laser Extensometer Advantages: in actual testing situation, the user will find the Laser Extensometer exhibits the following characteristics:

Safety: The United Laser Extensometer emits visible laser light at powers levels comparable to the average supermarket barcode scanner.

Versatility: It is able to accurately measure a wide variety of materials including high modulus composites, metals, plastics and elastomers. With a suitable environmental chamber that provides a window for external scanning, high temperature (700+Deg F.) and low temperature testing present no specific difficulties. As with other non-contact methods, testing through to specimen break without having to remove a mechanical extensometer is a definite advantage.

Easy Setup and Use: Because the scan line is visible to the user, the Laser Extensometer is easy to aim; there are no special viewing lenses required. If a high elongation test is to be performed or an extra-long gage length is needed, the unit is simply moved back, further from the specimen. There is no need to maintain a suite of interchangeable lenses to accommodate different test setups,
